What is virtual testing

Virtual testing is a process in which your product is tested on various characteristics, such as drop resistance, failure behaviour or deformations. Numerical models are used to verify the performance of the product.

Why virtual testing?

Virtual testing can save a lot of your time and money. Virtual testing can reduce your time-to-market and eliminates the need to adjust design parameters in a late stage of development. This avoids unnecessary costs and frustration.

Virtual testing: how?

Reden builds a virtual model of your product. Most of the tests you perform on your physical product can be performed by us on the virtual product. As a result, you need fewer prototypes and less testing. If the virtual model does not meet the desired performance, we adjust the parameters until the product has the desired properties.

What can Reden test in a virtual model?

We can simulate almost any aspect of mechanical behaviour, such as movement, deformation, stiffness and strength, friction, impact, etc. We can always approximate the behaviour of the physical product through modelling and simulation to achieve the desired results.

What does it mean for the designer?

Getting it right the first time! Modelling & simulation- in other words: virtual testing- gives you insight into the relationship between performance and design parameters. This insight enables you to take sound decisions about the feasibility of concepts in the design phase. Therefore you need to build fewer prototypes and physical models. The insight can be consolidated and used to make better products faster.

Why Reden?

Our approach makes your knowledge advance by leaps. Your design decisions will be taken with a firm basis in knowledge. The widely used trial-and-error method is abolished, which saves a considerable amount of time and money.

Why virtual testing, and what is it?

Virtual testing is a process in which your product is tested on various characteristics, for instance drop resistance or pressure characteristics.

The process of development has several stages. It starts with an idea and product knowledge, followed by a succession of steps, such as design (concept generation, test models), prototyping and pilot production. Eventually, production follows (practice). Ultimately, the goal of every product is to meet the agreed performance criteria. A football should be able to bounce, a pump to pump, for a specified time. A production machine should be able to have a certain accuracy. The actual performance becomes apparent, however, only when the product has been (partly) completed. What if it does not perform well enough? You start again and repeat the cycle until you succeed? The risk of a prolonged process of trial and error is real, because you do not always know exactly "which knobs to turn" to get the desired performance. Lack of time or knowledge may force you to settle for a sub-optimal results! The whole process can become much faster, cheaper and better by using virtual product testing.

How?

Reden builds a virtual model of your product. Most of the tests you perform on your physical product can be performed by us on the virtual product. This means you know in the design phase whether or not your product will achieve the desired performance. In this phase of the process, you can change one or more parameters and repeat the virtual testing until the performance is all right. The cost of modifying the design in this phase is a fraction of the cost of redesigning a product in the prototype phase. Thanks to the virtual model, we know exactly which design parameters affect the performance and which modifications are most effective to optimise the product performance.

To what can we apply virtual testing?

We can simulate almost any aspect of ‘mechanical’ behaviour, such as:

motion

deformations

stiffness and strength

friction

impact analysis

dynamic behaviour

accuracy

vibrations / resonance frequencies

fatigue and life time

crack growth

heating, cooling

fluid flow

magnetism

seismic effects

manufacturing processes

Material behaviour that we can take into account:

large deformations / non linear behaviour (material & geometry)

rate dependency / viscoelastic behaviour

history dependent / plastic deformation

advanced materials / composite structures

failure behaviour and failure mechanisms

What does it mean for the designer?

Using our models (virtual version of your products), we can give you insight in the relation between the design parameters and the product performance. We can investigate the sensitivity of the performance on variations of a certain parameter. Moreover, we can determine the limits within which a parameter must be specified in order to achieve the required performance with a high degree of robustness (6 Sigma). Variations in the product due to variations in the production process can also be included.

In short, virtual testing (modelling and simulation) gives you insight into the relationship between performance and design parameters. This insight enables you to take sound decisions about the feasibility of concepts in the design phase. Therefore you need to build fewer prototypes and physical models. The insight can be consolidated and used to make better products faster.

Why Reden?

Reden approaches development scientifically without being too academic or head-in-the-clouds. We remain pragmatic and aim for both short and long term results. Our approach makes your knowledge advance by leaps. Your design decisions will be taken with a firm basis in knowledge. The widely used trial-and-error method is abolished, which saves a considerable amount of time and money.
